How can I correct the permanent damage to my lips from years of them being overfilled?

Only on the basis of in person evaluation one could give you possible options. In person consultation with a board certified plastic surgeon is recommended. Good luck.

Unfortunately, you have not provided photographs. There are several options but need more information to give a more accurate answer.

I would dissolve slowly over time to allow your skin to retract in between treatment and for your to get used to the look. Skin takes up to 6-8 weeks to start shrinking. After 7 years and multiple syringes, you might benefit from increment dissolving. Hope this helps.

We can’t really make an assessment without seeing pictures. If you’ve stretched out your lip tissue from overuse of fillers than that it’s now what your lips look like. Fat transfer may be an option or continue using fillers in a more conservative manner.
